PUT IN A 95 BIGBORE KIT AND GEARDRIVE CAM KIT RODE ABOUT A 1000 MILES NOW LEAKING OIL FROM BOTTOM OF CASES WERE THEY MEET NOT SURE HOW OR WHAT HAS CAUSED IT
i learned a long time ago, never freshen up the top end without also tightening up the bottomend. Blew a 350 Chevy apart doin that years ago.Only a guess, but you have a fresh top end and old worn bottom end? Maybe your new found power is wreakin havoc on your worn bearings and bushings below.

Your fix is to split the cases amd seal them with silicone I like the blue ATV stuff. Maybe rtv hell I don't know. The stuff is blue and made for high heat applications. By: MarkGoff on: 3-5-2010
